Answer:

n = 6 $\sqrt{3}$

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{\sqrt{3} }{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{n}{12}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2n = 12 $\sqrt{3}$ ( divide both sides by 2 )

n = 6 $\sqrt{3}$

The currency in switzerland is called a franc. On a certain day, one U.S. dollar equaled 1 1/4 swiss france. Write and solve a m

Rufina [12.5K]

Answer:

The equation is x = y * 4/5 and US$ 12 would equal 15 Swiss Francs

Step-by-step explanation:

1. Let's review all the information provided for solving this question:

1 US$ equivalent to 1 1/4 Swiss Franc

2. Let's write and solve a multiplication equation to find the amount of US$ that would equal 15 Swiss Francs

x = Amount of US$ equivalent

y = Amount of Swiss Francs

x = y /1.25

x = y / 5/4 (1.25 = 5/4)

x = y * 4/5

Now, let's replace with the real values:

x = 15 * 4/5

x = 60/5

x = 12

US$ 12 would equal 15 Swiss Francs
